Well, NST's aren't terribly hardy. When you hook up an NST or even a pole
pig to a capacitor as in tesla circuits, they tend to develop Higher than
normal voltages. The pole pigs are hardier and can handle some higher than
normal voltages but not so with the NSTs.

What happens is that with an assync rotary, the contacts are often not close
enought to fire when the voltage reaches the peak, and it sometimes it can
resonate like waves in a bathtub that slosh water over the side.

With a sync rotary, the motor is specially modified to run at a speed that
ensures that contacts come into proximity to each other at 120 times per
second, at the moment when the voltage reaches the peaks.

You can use an assync gap with NST's IF you make up full wave rectifiers and
feed the current to the gap in DC form.
